Problem shaping means revising a question so that the solution process can begin or continue. It is part of the larger problem process that includes problem finding and problem solving. Problem shaping (or problem framing) often involves the application of critical thinking. Algorithmic approach to technical problems reformulation was introduced by G. S. Altshuller in ARIZ. Problem finding means problem discovery. It is part of the larger problem process that includes problem shaping and problem solving. Problem finding requires intellectual vision and insight into what is missing. This involves the application of creativity. Finding a problem can, depending on the problem, be either much easier or much harder than solving the problem. An example of a problem that was much easier to find than to solve is Fermat''s Last Theorem. The problem is simple, is it true that it is impossible to separate any power higher than the second into two like powers? Solving the problem took 357 years.
